The RNA World

formerly hosted by Leibniz Institute for Age Research – Fritz Lipmann Institute Jena.

The RNA World Website provides a collection of links to RNA-related information. It was launched in 1995 and has been maintained over the years by Jürgen Sühnel affiliated with the Leibniz Institute for Age Research – Fritz Lipmann Institute (FLI), formerly known as Institute of Molecular Biotechnology (IMB), located in Jena/Germany. From now on, responsibility is taken over by Manja Marz.
